Your code,
no limits.
Standalone programmer for STM32 and ESP32 microcontrollers. Straight to the hardware, no PC, no drivers, no development environment.
Total autonomy
No PC, no drivers, no development environment at each workstation. An OLED display and two buttons — Sel / Ok — cover the whole process.
Capacity and organization
The microSD stores thousands of programs and lets you organize them in folders: by customer, product or revision.
Portability
Runs on any USB power bank. Update firmware in the workshop, on the production line or in the field.
Two families, one tool
STM32 over SWD and ESP32 over UART. Same 2.54 mm connector, same procedure, same tool.
Four steps. Zero computer.
The whole process, from firmware to programmed board, without touching a mouse.
Copy the .bin to the microSD
From any computer, just once. The card stores thousands of programs organized in folders.
Select the file
Browse folders with Sel. Confirm with Ok. The OLED display shows the full path before programming.
Connect the target board
1.5 m cable to the 2.54 mm connector. SWD for STM32, UART for ESP32. Same connector, same gesture.
Program and repeat
Unit after unit, without going back to the workstation. The device handles the whole programming process on its own.
USB power bank. Production line. Workshop. Wherever it is needed.

Technical questions.
No. The firmware is copied to the microSD from any computer just once. The device does the programming by itself: an OLED display and two buttons — Sel / Ok — cover the whole process.
